ROLL CONSTRUCTION.

Application filed February This invention relates to roll construction and particularly to rolls such as are used in printing, embossing and engraving.

One ot the objects ot the invention is to provide a roll of the type described constructed to withstand strains and stresses to which the roll is subjected and, furthermore, to provide a roll that will preserve true alignment and will not be Warped.'

Another object of the invention is to provide a roll of the type specied having truss means adapted to withstand the deflecting 'and deforming stresses on the roll where the strain is greatest and to distribute the strain throughout the length of the roll.

Another object of the invention is to provide a roll so constructed that the shell can be easily and readilremoved from the supporting structure t ereby facilitating the changing of patterns.

Further objects ot the invention Will appear from thet'rollovving specification taken in connection with the drawings, which form a part of this application, and in Which- Fig. 1 is a longitudinal elevation partly in section of a roll constructed in accordance with the invention. Y

Fig. 2 is an end vievv of the structure shown in Fig. 1.

Fig.l 3 is a transverse sectional elevation talen substantially on line 3-3 of Fig. l, an

Fig. e is a transverse sectional elevation taken substantially on line 4 4. of Fig. 1.

The invention briefly described consists of a roll comprising a shell, truss means Within the shell for supporting the shell and a plurality of members intermediate the inner surface of the shell and the truss means, for bracing the shell and rigidly and firmly supporting the shell on the truss means. ln the vform of the invention illustrated Wedges are used intermediate the truss means and the shell, the Wedges being adjustable into tight engagement with the shell and truss means. Further details of the invention Will appear from the following' description.

In the particular embodiment of the invention shown, comprising a cylindrical body 10 and a shell 11 Which is forced or shrunk on the b ody 10. When used Jfor printing, the body 10 1s preftruss members 12 and 13 having their bases the roll has an outer shelly 2, 1925. Serial No. 6,169.

erably cast iron and the shell 11 is formed of copper or other material suitable for engraving, etching or embossing'. vIt desired, the body 10 of the roll may be formed of copper or similar material, thereby eliminating the outer shell 11.

The roll is supported on Aa pair of conical abutting as shown'at 14, the bases of the conical members being connected in any suitable manner as by a series of bolts 15.

The apexes of the conical members are extended to form sleeves 16 which are threaded as shown at 17.

ln order to insure the proper alinement of the shell body 10 on the truss members and to' firmly and rigidly secure'the shell in position, there are provided a plurality of Wedges 20, each Wedge having a plurality of spaced projecting portions or lugs 21, 22 and 23. The Wedges 20 are so constructed as to t on the outer surfaces of the truss members 12 and 13 and the projections or lugs 21, 22 and 23 have their outer ends 24 so formed as to always be disposed parallel to the aXis of rotation of the shell and axis (lig rlttation of the truss supporting means 3 As illustrated in Figs. 1 and 3, the outer surfaces of the truss members have grooves 25 formed therein or receiving the Wedgesv and also have secured thereto a plurality of pairs of cap screws 26, 27 to retain the Wedges in position on the truss members. The Wedges 20 are adjusted into tight engagement with the truss members and With the interior surface of the shell 10 by means of heads -30 which are threaded on the sleeves 16. The heads engage the wedges to force the Wedges into thedrum at 31 and in order to facilitate the Withdrawal of the Wedges, the projections 21 on the wedges are provided With inwardly extending lugs 32 which overlap the ,outer periphery .of the heads 30. The heads have openings 33 formed therein for the insertion of a tool to facilitate the rotation of the heads. j l The hubs 34' of the heads are threaded as shown at 35 to receive cover p1ates36 which are preferably provided for the purpose of preventing ink or foreign substances 105 from entering the ends of the shell.

firm and secure engagement With the interior of the shell body lO and with the truss members l2 and 13. The cover plates 36 are then moved to a position to close the ends of the shell. When the shell is to be removed, the cover plates are first removed and the heads 30 are then rotated to'draW the. Wedges outwardly thereby re' leasing the shell Which can then be Withdrawn from the supporting structure.

The shafts on which the shell is mounted as shown at 40 and 41 are journaled in the sleeves 16 of the truss members.

Although one specific embodiment of the invention has been particularly shown and described, it Will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made Without departing from the spirit or scope of the invention, as eX- pressed in the following claims.
